About SEDS

The State Energy Data System (SEDS) is the source of the U.S. Energy Information Administration’s (EIA) comprehensive state energy statistics. EIA’s goal in maintaining SEDS is to create historical time series of energy production, consumption, prices, and expenditures by state that are defined as consistently as possible over time and across sectors for analysis and forecasting purposes.

While some SEDS data series come directly from surveys conducted by EIA, many are estimated using other available information. These estimations are necessary for the compilation of "total energy" estimates. The data sources and estimation procedures are described in the technical notes. We welcome your suggestions on ways to improve our estimation methodologies.
